Eukaryotes

Prokaryotic - no nucleus

Eukaryotic - nucleus

  • single cell and multicellular

Autotrophic - makes own energy

Heterotrophic - cannot make its own energy

Domain Eukarya

  • Cells are complex w/ more organelles than bacteria, or Archaea

  • most produce sexually, some asexually

  • includes kingdoms protista, fungi, plante, and Animalia

Kingdom Protista

  • different to define

  • all other Eukaryotic kingdoms evolved from a type of protist.

  • most are single cellular, do have complex organelles that bacteria and Archaea lack

Plant like protists

algae, kelp, phytoplankton are protists that photosynthesize. (responsible for 70% of Earth’s photosynthesis)

Animal-like protists

  • primary consumers that move toward prey

  • mostly aquatic

  • paramecium, amoeba, and intestinal parasites

  • wrap around, and digest prey

Fungus like protist

  • heterotrophs & decomposers

  • release enzymes to digest externally

  • reproduce using spores

Kingdom Plante

  • parasitic or carnivorous

  • sessile & multicellular

  • have cell walls, chloroplasts, and vacuoles

  • reproduce by spore and gamete formation

  • 4 major groups

Non-Vascular Plants

  • bryophytes

  • most primitive (lack roots, stems, leaves)

  • NO vascular system

  • moist environment, low-lying & ground hugging

  • no seeds, reproduce via spores

  • (moss, hornwarts, liverwarts)

Seedless Vascular Plants

  • have vascular system, but don’t produce seeds

  • reproduce through spores

  • have true roots, stems, leaves

Gymnosperms

  • pollen delivers sperm to eggs by wind

    • seed that contains plant embryo, food supply (pine trees, spruce firs)


Angiosperms

  • have flowers

    • need pollinators (bees) for reproduction

    • make up most of our food crops

    • (cacti, roses, apple trees, shrubs

Kingdom Fungi:

  • Heterotrophs and Sessile (consumers)

  • cannot do photosynthesis

  • mostly multicellular

  • reproduce asexually or sexually using spores

Roles

  • can cause diseases (mold, mildew, athletes foot, diaper rash)

  • yeast (food)

  • antibiotics are made from Fungi

  • can have symbiotic relationships w/ organisms

Kingdom Animalia

  • all are multicellular, heterotrophs & mobile

  • most reproduce sexually, some asexual

  • respond to external stimuli

  • incredibly diverse

  • most are vertebrates or ocean dwellers

  • 32 recognized phyla

Phylum Porifera (Sea sponge)

phylum cnidaria (jellyfish)

phylum plktyhelminthes (flatworms)

phylum annelila (segmented words)

phylum Mollusca (gastropods)

phylum arthropod

phylum echinodermata (sea stars, urchins)

* phylum chordata (dorsa nerve cord, notochord, post anal tail) (Humans)

phylum chordata - vertebrate

classification of fish

class amphibia

class reptillia

class aves

class mammaria
